Background
At present, the operation mileage of the Chinese high-speed rail reaches 3.5 kilometers, the operation mileage and the speed are the first in the world, and in the latest planning outline of the national iron group, the mileage of the Chinese high-speed rail reaches 7 kilometers by 2035 years, all cities with more than 50 million population need to be communicated with the high-speed rail, and the convenience of the high-speed rail in travelling is deeply loved by the public.
In order to ensure the current collection performance of the pantograph-catenary under the condition of high-speed operation, the high-speed railway contact networks with the speed of 250km/h and above all adopt elastic chain-shaped suspension in China at present, namely, elastic suspension ropes are arranged at suspension points. Meanwhile, in order to meet the requirement of high-speed operation of a high-speed rail, the contact net is required to keep high smoothness, the height difference of two adjacent contact lines in 1 span is required to be not more than 10mm, the contact lines reach the standard in acceptance, and the precision required in site construction is not more than 5 mm.
The height of the contact line is controlled by the length of the integral suspension string, and the elastic suspension cable is additionally arranged at the suspension point of the high-speed railway in order to keep the contact line smooth and keep the bow net current-receiving performance at the suspension point. The addition of the elastic sling makes the calculation model of the whole sling very complicated. Therefore, measurement of calculation parameters of the whole dropper, data sorting and input rechecking, software length calculation, prefabrication and installation are extremely important works. The precision of the calculation of the length of the whole suspension string directly determines the repeated workload of replacement and suspension adjustment of the suspension string during site construction, and further directly influences the construction period and the construction quality of a contact network.
The construction method of the prior measurement and calculation of the parameters of the integral dropper is that a precise measurement group is specially formed, tools such as a DJJ-8 laser measuring instrument, a steel tape, a track gauge and the like are adopted to measure and calculate required basic data, such as the height, the superelevation, the span and the like of a catenary, a plurality of persons measure and record, after the field measurement is returned, data arrangement is carried out, after the arrangement is finished, a special person inputs the data into various data required by calculation software by combining with a contact net plan, generally one person inputs the data, one person rechecks the data, after the correctness is confirmed, the calculation software is operated to calculate, a calculation result is output, and the integral dropper is prefabricated by a pre-assembly center and then is installed.
At present, the DJJ-8 laser measuring instrument is adopted to measure the height, which belongs to single-point measurement, the action of re-rising the lower bow waist is repeated once when measuring one point, taking Yuke as a special example, the whole line is about 10 ten thousand of integral dropper, each measurement needs 10 ten thousand of actions of re-rising the lower bow waist, and the height of the contact line at each dropper needs to be repeatedly measured for many times, so the labor intensity of measuring personnel is very large. Measuring one anchor segment takes 1 hour and a measurement team takes more than 16 people.
The existing measurement data recording, sorting and inputting calculation software adopts a manual operation mode. The time consumption is long, generally 1 hour is needed for sorting and inputting calculation software, 2 hours is needed for rechecking whether data are accurate, human errors are prone to occur in the data recording process, errors are prone to occur in the measured data inputting process, and errors occur when the calculation results are wrong due to data sorting errors or data inputting errors, so that errors after the integral dropper is installed exceed the standard and rework is caused.
Therefore, in order to solve the problems, the invention provides an integrated application method for measuring and calculating the whole dropper of the high-speed rail contact network.

F. and the integral dropper calculation software calculates and outputs dropper prefabrication parameters after selecting and inputting or automatically reading calculation table data in an Excel format.
When the embodiment is used, the DJJ-8 laser measuring instrument is adopted to measure the dropper parameters before replacing and prefabricating the whole dropper of the contact network in the prior art to carry out single-point measurement, the action of lowering the bow and then rising the bow once is repeated for each measured point, and the working strength of measuring personnel is high. Taking Yuke speciality as an example, the whole line is about 10 ten thousand of integral suspension strings, each measurement needs 10 ten thousand of actions of lowering the bow waist and then rising, and the height of the contact line at each suspension string needs to be repeatedly measured for many times, so the labor intensity of measuring personnel is very high. Meanwhile, the single-point measurement mode in the prior art requires long time for measurement, more measuring personnel are needed, at least 1 hour is needed for measuring one anchor section, and more than 16 people are needed for one measuring group. A large amount of manpower and material resources are wasted in the measuring mode, and meanwhile, the measuring efficiency is low, and the requirement for efficient production development is not met. Therefore, this embodiment has proposed to calculate required each item parameter with whole dropper of contact net of whole anchor section change whole dropper with contact net full parameter developments intellectual detection system device and has measured. Specifically, the hand-push type dynamic intelligent detection device for the full parameters of the overhead line system is used for measuring by pushing the dynamic intelligent detection device for the full parameters of the overhead line system by 1 person along the rail, and the whole measuring process can be completed by monitoring by 1 person. In addition, in the measuring process, the measuring personnel do not need to carry out the work of lowering the waist and then rising the waist one by one, the labor intensity of the measuring personnel and the number of the measuring personnel are reduced, the measuring efficiency is improved, the labor force is saved, and therefore the cost is reduced.
Before measurement, construction preparation is firstly needed, and the preparation mainly comprises the following preparation:
firstly, preparing the technology in the industry, namely compiling an operation instruction book, organizing technicians to learn before starting work after the operation instruction book is compiled, and familiarizing with specifications and technical standards. And (5) formulating construction safety guarantee measures and providing an emergency plan.

And secondly, preparing personnel, namely constructing a professional measuring group and a professional calculating group, and respectively measuring the whole dropper of the high-speed rail contact network and calculating the measured data.
Thirdly, erecting the instrument, namely checking whether each part of the full-parameter dynamic intelligent detection device of the contact network meets the use requirement before using, then assembling the battery of the full-parameter dynamic intelligent detection device of the contact network, stably placing the full-parameter dynamic intelligent detection device of the contact network on a rail, taking care that the radar side is far away from a pillar during placement, firstly leaning a gauge measuring wheel on the inner edge of the rail, then clamping a fixed side into the inner edge of the rail and abutting against the inner edge of the rail, and finally adjusting and opening a support rod to finish the erection of the instrument.
And after the instrument erection is finished, the parameters required by calculation of the whole dropper of the contact network, which needs to replace the whole dropper at the whole anchor section, can be measured by using the whole parameter dynamic intelligent detection device of the contact network. The measured data in the measuring process can be displayed on a display screen in real time.
The contact net full-parameter dynamic intelligent detection device comprises a walking assembly and a data acquisition assembly arranged on the walking assembly, wherein the walking assembly is composed of insulating nylon walking wheels, the insulating nylon walking wheels are arranged on a track, and the data acquisition assembly comprises a laser radar, a high-precision tilt sensor and a displacement sensor. The laser radar is used for scanning the contact network to acquire data of geometric parameters of the contact network to be detected; the high-precision tilt angle sensor is used for measuring the superelevation and the track gauge of the track of the measured line.

The traditional limitation that measurement can only be carried out in a skylight point is eliminated, the operation time point of contact net dropper parameter measurement is enlarged, and the measurement convenience is improved.
In addition, in the prior art, measurement data in the single-point measurement process needs to be manually recorded by a measurer, and after the measurement is finished, the measurement data is collated by the measurer and manually recorded into a computer to calculate the prefabricated parameters of the dropper by using integral dropper calculation software. The data processing mode of manually recording, sorting and inputting data is long in time consumption, generally sorting and inputting calculation software needs 1 hour, whether data is accurate or not needs 2 hours is rechecked, meanwhile, human errors are prone to occur in the data recording process, errors are prone to occur in the measured data inputting process, and errors of calculation results are prone to occur due to data sorting errors or data inputting errors, so that the errors after the integral dropper is installed exceed the standard and rework is caused. In order to solve the technical problem that errors may occur when measuring personnel manually records and inputs measurement data, in the embodiment, the measurement data in the detection process is stored in a full-parameter dynamic intelligent detection device of the overhead line system and is stored as a db data file, and after the detection is completed, the measurement data in the db data file is directly exported to a full-parameter dynamic intelligent detection background software system of the overhead line system. The process reduces the link of manual recording, thereby reducing the possible recording errors of the measured data in the measuring process and improving the accuracy of the measured data. And after the measurement data are exported, importing the measurement data into a contact net full-parameter dynamic intelligent detection background software system to perform data processing on the measurement data, and generating a calculation table in an Excel format after the processing.

In the process, the measured data is input-free and led into the whole dropper calculation software, and the link of manually inputting the measured data is reduced, so that the possible errors caused by manual input are avoided, and the prefabrication accuracy of the whole dropper of the high-speed rail contact network is further improved.
